For me to tell you that I would have to know like how you are planning on playing all the pokemons of your team.
But Sceptile can get walled easily.
A physical Sceptile, with SUB+SDs may take down Registeel, but special Scep has nothing to take down Registeel.
I know you have other physical sweepers but Registeel could still wall you.
Wil-o-Wisp would be problematic for you aswell, as you have 4 physical sweepers.
I think you would need to start from the beginning and work your way through the team again.
